Video/New Media Workshop Lesson Plans (part four)




Discover Persistence of Vision Thaumatropes and Flip-book Animation



Objective:
Participants will discover the phenomenon of Persistence of vision threw hands on experience. They will each create thaumatropes and flip book. These activities will create a basis for the understanding of how film and video works. They will also learn a rough early history of cinema.

Materials:
Disks made from ¼ inch birch plywood, yarn, ribbon, eyelets, mod-podge/clear coat spray, sand paper, paint pens, acrylic paint, colored sand, fine glitter, small rind stones, bangles, sequins, collage materials, brushes, old photographs, scissors, pre made flip books, ink pens colored pincels, journals

Warm-Up:
Play with thaumatropes that the art play team has made. After Image Exercise Participants will make thaumatropes from wooden disks. Participants will make traditional and non-traditional flipbooks.

Follow-up:
Personal art experience journaling exercise: Participant should write one to ten lines about their experience in class. Sample questions to answer: What was my favorite thing about today’s class? What did I not enjoy about today’s class? What are 3 things I learned? What are 3 things I am proud of? How did I feel after today’s class? Is there any thing that I want to state about my art piece? Note: if the child is not developmentally capable of writing it is encouraged that the child draw a picture or verbalize what they would like to be written and it be transcribed by a volunteer.


Historical/Conceptual Notes:
Persistence of vision is the phenomenon of the eye by which an afterimage is thought to persist for approximately one twenty-fifth of a second on the retina.
A thaumatrope is a toy that was popular in Victorian times. A disk or card with a picture on each side is attached to two pieces of string. When the strings are twirled quickly between the fingers the two pictures appear to combine into a single image due to persistence of vision.
The invention of the thaumatrope is usually credited to either John Ayrton Paris or Peter Mark Roget. Paris used one to demonstrate persistence of vision to the Royal College of Physicians in London in 1824. He based his invention on ideas of the astronomer John Herschel and the geologist William Henry Fitton, and some sources attribute the actual invention to Fitton rather than Paris. Others claim that Charles Babbage was the inventor.
Examples of common thaumatrope pictures include a bare tree on one side of the disk, and its leaves on the other, or a bird on one side and a cage on the other. They often also included riddles or short poems, with one line on each side.
Thaumatropes were one of a number of simple, mechanical optical toys that used persistence of vision. They are recognised as important antecedents of cinematography and in particular of animation.
The coined name translates roughly as "wonder turner", from Ancient Greek: θαμα "wonder" and τρόπος "turn".
A flip book or flick book is a book with a series of pictures that vary gradually from one page to the next, so that when the pages are turned rapidly, the pictures appear to animate by simulating motion or some other change. Flip books are often illustrated books for children, but may also be geared towards adults and employ a series of photographs rather than drawings. Flip books are not always separate books, but may appear as an added feature in ordinary books or magazines, often in the page corners. Software packages and websites are also available that convert digital video files into custom-made flip books.
Flipbooks are essentially a primitive form of animation. Like motion pictures, they rely on persistence of vision to create the illusion that continuous motion is being seen rather than a series of discontinuous images being exchanged in succession. Rather than "reading" left to right, a viewer simply stares at the same location of the pictures in the flipbook as the pages turn. The book must also be flipped with enough speed for the illusion to work, so the standard way to "read" a flip book is to hold the book with one hand and flip through its pages with the thumb of the other hand. The German word for flipbook—Daumenkino, literally "thumb cinema"—reflects this process.
